Groop was a female mole Dibbun of Redwall Abbey. When Sister Doral played her fiddle during an afternoon tea on the Abbey lawn, Groop and the other Dibbuns danced joyously. They even coerced the birds, Pandion Piketalon and Brantalis Skyfurrow into joining them, and Groop and squirrelbabe Taggle tried to teach them their dancing techniques.
